OpenTelemetry baggage dropped across Slick AsyncExecutor (span propagates, baggage does not)

Describe the feature you'd like

I'd like to capture and restore the full Context in SlickRunnableInstrumentation. Right now it only stores the span ((https://github.com/DataDog/dd-trace-java/blob/v1.59.0/dd-java-agent/instrumentation/slick-3.2/src/main/java/datadog/trace/instrumentation/slick/SlickRunnableInstrumentation.java), so anything else attached to the context(notably OTel baggage) is dropped across a Slick action.

It appears as though AdviceUtils.capture() only stores Span. Since Baggage is a separate keys in datadog.context.Context, it gets dropped at this boundary.

Hi @henry-macarthur - we're currently migrating non-HTTP and async instrumentations over to the new Context API which supports both spans and OTel baggage. We'll update this issue when the Slick instrumentation has been migrated.
